Reset event serial ids after re-import.

Browse Source 
When the database is recreated, the sequences
used in the events_timed and events_seq tables
will be at their initial values, which will
almost certainly conflict with existing data
when it is imported via COPY.

With this commit, we set the current value for
those sequences to something usable.

Fixes #33.
